However, the installation packages for Oracle JDK 7 available at Java SE Development Kit 7 - Downloads | Oracle Technology Network | Oracle show i585 package names.
Actually they show 'i586' in some names.
Should they not be called i686 to be correct?
Probably - it if concerns you that much just use one of the 'contact us' links on that page and report it to Oracle.
Thanks for your response. I'm just writing some documentation and noticed this about CPU requirements. I would not want to write about something that isn't true or clear, but decided to leave it out and instead provide the link to the Oracle documentation. Someone else can sort it out.
